β Useful for werewolvesβ ! π€£ Do you have the reference numbers ?
Although I'd argue, any watch with a moon phase indicator is useful for werewolves.
#3 197β618 uses a 699/2 case, but is a unique version. #5 861β389 is ref 853 (unique never sold) #6 ref 871 (3+ made) #8 best known as the Calibre 89 (5ish made) #9 best known as the Star Caliber 2000 (24 made) Others donβt have reference numbers.
I particularly like nΒ°6: no time, pure calendar. And the decade indication. Cheers.
The time is set on the back (or I guess, the front)
A very informative and entertaining-humorous post. Thanks a lot for that! π All the best Thomas
